What terminology does Article 690 use for the grid receiving power from a PV system?

Article 690 of the National Electrical Code refers to the grid that receives power from a photovoltaic (PV) system as the utility grid. This terminology is aligned with standard industry practices, where the utility grid represents the network of electrical distribution that delivers power to consumers from utilities.

The utility grid is responsible for the distribution of electricity generated from various sources, including solar energy, and it plays a crucial role in integrating renewable energy systems. When a PV system generates excess electricity, it can be fed back into the utility grid, providing benefits such as energy credits for the system owner and enhancing overall grid stability.

Understanding this terminology is vital for compliance with the NEC and for ensuring clear communication about the electrical systems involved in renewable energy generation. Other terms may be relevant in different contexts, but within the scope of Article 690, "utility grid" is the precise terminology used.
